crowfish Posted January 12, 2017 Share Posted January 12, 2017 Any chance there's a shell hanging on to this ammonite? I'm talking about the protrusion on the bottom right, at 5 o'clock. Link to comment Share on other sites More sharing options...
FossilDudeCO Posted January 13, 2017 Share Posted January 13, 2017 can we get some more pictures, maybe a bit closer up and with a scale? Link to comment Share on other sites More sharing options...

Although it's possible to enlarge the photo here, the details are too fuzzy. Well-focussed closeups would be much better. Greetings from the Lake of Constance.

Ludwigia Posted January 16, 2017 Share Posted January 16, 2017 That could be a mold of part of the venter of another ammonite. There's no shell substance there at any rate.

BobWill Posted January 16, 2017 Share Posted January 16, 2017 Yes that does appear to be an internal mold of a broken piece of ammonite on your ammonite. Judging by the shape of the ribs I would guess Idiohamites fremonti. Link to comment Share on other sites More sharing options...
